Captive Portal capabilities

Have you thought about adding Captive Portal capabilities to the software.

I know there is the web redirect ability but it would be good to be able to setup a Captive page when first trying to access the internet, kinda like "your payment is due" then "click here to continue" type page.

I'm sure there would be different requests on this feature but a simple redirect to a web page (whether internal or external) with a counter that could be reset manually or at set times that directs people to an initial page (such as "payment due" or "accept terms"or whatever with a "click here to continue normal browsing&quot.
The reset counter would take them back to the initial captive page.
